This invention relates to window frame constructions and comprehends the provision of an improved frame wherein the window or sash can be readily removed.

An object of this invention is to provide a window frame construction wherein the frame includes means for permitting the ready removal of the window for cleaning or other purposes without the necessity of removing one or more of the window stops mounted in the window frame.

Another object of this inventionis to provide a window frame construction of this kind which is so constructed that the frame will not be weakened unduly through the provision of the means herein disclosed for removably mounting the window within the frame.

The above and various other objects and advantages of this invention willin part be described in and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing, wherein F igur 1 is a sectional view partly in detail of a window frame constructed according to the preferred embodiment of this invention;

Figure 2 is a vertical sectional'view taken on the line 2-2 of Figure 1;

Figure 3 is a sectional View taken on the line 33 of Figure 2.

Referring to the drawing wherein like characters of reference designate corresponding parts throughout the several views, the letter F desi nates generally a window frame construction including side frame members 10, an inner stop member 11, a parting stop 12 and'an outer or blind stop 18. v

The side frame member 10 has a passage 14: through the upper end portion thereof within which a. sheave or pulley is mounted for training a weighted rope thereover soas to balance the window sash within the frame F.

That portion of the side frame member 10 between the inner and the parting stop members 11 and 12, respectively, and between the parting and the outer or blind stop 13 is grooved or inwardly offset, as at 15, and the length of this rabbet or offsetportionis preferably substantially equal to the length of the stop memhers 11,-12 and 13. r I The filler or removable plate 16 is removably mounted in this rabbete'd portion 15 and when'so mounted, the outer surface of the filler plate16 is substantially coplanar with the adjacent face ofithe side frame member 10 so that the window sash can readily slide up or down within the groove formed between two of the stop members. This filler no or bar 16 is provided with an aperture-17 therethrough and a securing member in the I form of a staple, nail orthe like 18, is mount- 7 ed in the sill portion 19 of the window frame and engages the lower end of the fillerv16 so that the filler will not readily come out of the rabbeted portion 15.

Preferably, the length of the filler 16 is slightly greater than the height of the window sash so that the upper end of the filler 16 (1 0 I is relatively free, but the'filler is shorter than the length of the rabbeted portion 15. In

order to provide means whereby the filler 16 may be readily removed from the rabbet' 15, I have providedfa tapering upper end portion 20 on the filler 16 so thatwhen the filler 16 has been moved upwar'dly, the lower end thereof will pass theftop of tlie-s'ecuringmember l8 and the lower end portion may then be'swung i outwardly ofthe rabbet 15 with the upper po' end thereofdisposed between the edge of the window sashand the side frame member 10. r In the use of thi's device, the window sash is slidably disposed between pairs of thestop members 11, 12 and 13, and the filler 16' will be disposed in the rabbeted portion 15 and held therein by contact with a portion of the window sash and through the medium of the securing member 18; When it is desired to clean the window, particularly on theoutside the filler 16 can be removed by moving it upwardly toa point above the securing member 18 and then inwardly. The window sash can then be lowered to the point where the upper end thereof will be coplanar or below the upper end'of the rabbeted portion 15, whereupon the window sash can be movedl'aterally so as to carry the opposite edge thereof outward of thejspace between adjacent stops carried by the side frame member 10'. The win- J00 dow sash can then be swung reversely, being supported by the conventional pulley cord carried on each side thereof.

It will be obvious from the foregoing that a relatively simple window frame construction has been designed wherein the sides of the vwindow frame will not be unduly weakened frame construction can readily be made out of either wood or'm-etal, and that awindow frame constructed according to the preferred embodiment of this invention may'have the usual removable stop members formed integrally with the sides, thereby reducing the cost of the window frame construction.

It is, of course, understoodthat various changes and modifications may be made in the details of construction anddesign of the 'above'specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

What is claimed is '1. In a window frame construction, a pair of side frame members, aplurality of parallel vertically extending stop members carried by the side members, each of said side-mem- 'bers having an inwardly offset rabbeted portion disposed betweenpairs of stops, said rabbeted portion terminating at one end intermediate the ends of'the side member and extending to the extremity of the opposite end of the side member, an elongated memthan the distance between the upper end of the strip and the ad] acent end of the rabbeted portion to permit removal of the strip by upward sliding movement followed by out-- ward movement.

' In testimony whereof I hereunto afiix my I signature. 7

her seated in the rabbe'ted portion and having the inner face thereof substantially coplanar with the adjacent face of the side 'niembe'r, said elongatedm'ember being of a thickness substantially equal tothe dept-h o'f the stop members, and means engaging the window sill for removably mounting the elongated member in the rabbeted portion, said elongated member having the inner surface thereof adjacent the upperend inclined upwardly and outwardly "to provide a reduced'upper end topermit removal thereof.

2."In aowindow frame construction,a pair of side members, a plurality of parallel ver- 'ticaly extending window sash stops carried "by the side members, said side members having a 'rabbeted portion of'a length substanv 'tially greater than the height of the window :s'ash, a narrow strip removably mounted in said rabbeted portion and having a'length less than the length of the'rabbeted portion, and means for removably mounting the'strip 1n the'rabbeted portion, said means includ- V :ing'a staple of a length when in position in W the lower horizontal portion of'the frame less
